About FuelCell Energy

FuelCell Energy is a pioneering company in the realm of clean energy solutions. Established in 1969, the company has positioned itself as a global leader in delivering innovative energy solutions that are both efficient and environmentally friendly.

Based in the United States, with headquarters in Danbury, Connecticut and additional production facilities in Torrington, Connecticut, FuelCell Energy serves diverse markets across North America, Europe, and Asia. Their presence is bolstered by strategic partnerships, such as their collaboration with a South Korean partner for Asian markets.

The company's services encompass a broad spectrum of advanced energy solutions, including utility-scale and on-site power generation, carbon capture, hydrogen production, and long-duration energy storage. With their proprietary SureSource systems installed over three continents, they have produced millions of megawatt hours of ultra-clean power, showcasing their commitment to sustainability and energy innovation.
